I've noticed that my clock has been jumping back an hour, or a minute; I think lately it's become more frequent. I've also been getting errors out of S3 standby mode (Dr. Watson post moderm... Win 32 error), however I don't know if this is related. Is it the CMOS battery? I figure it's a possibility since the computer is around 4 years old. Any advice would be appreciated. System: Dell 8300, 2.6 GHZ, Pentium 4, 1.5 gigs ram
